migration - 2025 ACF Regionals

Question

Answer the following about discoveries in ecology achieved by studying butterflies, for 10 points each.

[10e] Until recently, monarch butterflies were thought to be the insect to undergo the longest type of this process. During this process, an organism travels across long distances, usually on a seasonal basis.

ANSWER: migration [or word forms; prompt on movement or navigation] (The insect with the longest migration is now thought to be the dragonfly species Pantala flavescens.)

[10m] This type of mimicry was first observed in the butterfly genus Heliconius. This type of mimicry relies on all involved species exhibiting aposematism and being unpalatable.

ANSWER: Müllerian mimicry

[10h] A study of the Glanville fritillary butterfly in Finland’s Åland Islands is the largest ever to examine these entities, which are approximated using the source-sink model. Richard Levins coined the term for these entities, which are patches of habitat linked by migration or dispersal of individuals.

ANSWER: metapopulations [prompt on populations]
